This one triggers an assertion in calculateSEHStateNumbers due to weird catchpad instruction in @_island_debug_invoke and many other functions.

Hi Sourabh, Thanks for raising this issue. To answer your question, (afaik) there isn’t anyone working on DW_AT_start_scope support in tree. We’re looking for a solution to this problem for Swift debugging, where it's important not to make a debug location for a variable available until its (guaranteed) initialization is complete. If at all possible, I’d /much/ rather we use the existing
